WHAT IS GALEX MISSION?

GALEX TELESCOPE

          Galaxy Evolution Explorer (GALEX) is an orbiting space telescope to conduct the first space UV sky-survey, observing galaxies in ultraviolet light across 10 billion years of cosmic history. It was launched into orbit aboard a Pegasus rocket on April 28, 2003.

GALEX TELESCOPE WHEN MADE

What Is The Objective Of The Mission?
              GALEX will produce the first comprehensive map of a Universe of galaxies under construction, bringing us closer to understanding how galaxies like our own Milky Way were formed. The spacecraft's mission is to observe hundreds of thousands of galaxies, with the goal of determining how far away each galaxy is from Earth and how fast stars are forming in each galaxy.

   How Does GALEX Do It?     
          GALEX will make observations at ultraviolet wavelengths to measure the history of star formation in the Universe. Since scientists believe the universe is about 13 billion years old, the mission will study galaxies and stars across about every 94 minutes and travels approximately 408,470 million miles per day

What Are The Findings Till Date?
       GALEX has been operating for over seven years, well beyond its nominal 29 month mission life. 
Over these years, GALEX has photographed
hundreds of millions of galaxies in ultraviolet light. Galaxies like M106, NGC 4248, dwarf galaxy UGC 7365 are some of the galaxies photographed. Over the past five years, the GALEX telescope has imaged half a billion objects over 27,000 square degrees of sky; equivalent to an area that would be covered by 138,000 full moons!
